Is there a way to have a child div of a main div hidden by default, only becoming visible when you hover over the main div?
I'm looking for a solution using Angular and avoiding the jQuery .hover() method.
My idea is to use ng-show on the child div and then update the binding when hovering over the main div. Is there a directive available to listen for hovering events?
You're definitely headed in the right direction. Utilizing the ngMouseenter and ngMouseleave directives will allow you to achieve this functionality.
<span ng-mouseenter="show = true" ng-mouseleave="show = false">
Mouse over me.
</span>
<div ng-show="show">Hello!</div>

@Swordfish0321 also makes a valid point - if you prefer, you can create a simple directive specifically for handling hover events, although it may not be essential. In projects like UI Bootstrap, we rely on mouseenter and mouseleave for tooltips.
Shout out to @JoshDavidMiller for a super concise response. I was trying to achieve this in an ng-repeat loop and couldn't quite crack the code on how to do it gracefully. Initially, using a boolean on the scope resulted in displaying edit controls for all items in the list instead of just the one I hovered over. I almost resorted to using angular.element (aka JQuery) and manually adding hover handlers so that only the controls for the hovered item would show. Thankfully, I didn't go down that dark path.
<div ng-repeat="item in items" ng-mouseenter="item.showEdit = true" ng-mouseleave="item.showEdit = false">
<span class="glyphicon glyphicon-edit" ng-show="item.showEdit"></span>
Hover over me.
</div>
The solution turned out to be simple - just attach the property directly to the item, rather than the $scope. In some cases where I couldn't add random keys to my list items, I mapped my array to a new one where the item became a property of a wrapper object. This way, I could add any properties to the wrapper object without cluttering the original item keys.
